GM factory bed liner is one of the best. It's extremely tough. I've had loads of sharp edged rock dumped into my bed multiple times...the bedliner doesn't seem to mind. Things slide on it quite well too. It is a rough texture and I wouldn't slide anything on it that is softer than the liner. If you want to transport nice wood furniture, etc, put a rubber mat in the bed. I'm honestly amazed that anyone would have any complaints about it.

22" wheels is insane. 18" is the sweet spot, big enough to accommodate good discs and rotors, but small enough to allow lots of sidewall. Sidewall is really important for a truck!

its looking like people are able to get 16-17mpg out of it, which is not bad and definitely better than the 6.0. Might even improve by 1mpg after 10,000 miles or so.

sounds about right.

22" wheels don't belong on a truck, IMO.

its true, the A8 has been one of the most temperamental transmissions in recent time. Not that it fails or requires significant maintenance, but it just isn't very smooth and is very prone to torque converter issues. There are TONS of people with the harsh downshift problem, far after learning has completed. It's something most people just live with, but with the new 19's coming out you'd think they would've fixed it. I personally think they looked at the problem, realized it would take a complete re-design to fix, and just said "screw it". Keep selling them for a couple more year then go to the A10. No sense in pouring money into it.

that sounds like a terrible idea if you just want a little more sound you should get a CAI instead

Yet another reason to wait 1-2 years after a new model comes out. That said, this is getting blown out of proportion. I won't make any judgement until I actually see a picture of a dented, punctured, or bent frame. If this is indeed a big problem, then it basically shows the trade off we are getting for the high MPG.

actually I don't think this is true. I looked at a T1 and a K2 truck today side by side at the dealer, and while the upper part of the bed is higher, the actual bumper and load floor of the bed are in fact lower on the 2019, which should make it easier to step up into the bed and load things into it.

This option is in the online "Build and Price" but it is under #7 Accessories under the "performance" tab. It's kind of confusing since the other "GM performance" options like Cold air intake, and performance exhaust, are selectable in the regular "packages" section of the builder, but the lift kit doesn't appear there, that I can see.

I cut a section off an old round table leg. A disc of hardwood about 4cm across and 1cm deep. Inserted at base of the plastic bracket assembly, pushed up behind it. To give yourself room to push it in, pull OUT on the gas pedal. Insert your chosen shim (imo, hardwood is the perfect material). Then let go of the pedal. The bracket will fall back against your shim and the flex will be gone. I didnt even have to secure my shim in place. It just sits up here behind the bracket. If you make it big enough, it just wedges itself in there and doesnt move. You cant see anything once its in either.

Bumping this thread because there has been some discussion about lack of power with the 5.3 liter. I firmly believe that everyone should implement the fix found in this thread regarding the gas pedal bracket flexing. It made my trucks "throttle response" much better--it was never an issue with AFM or the engine/tranny, it was the gas pedal flexing!!

Seat height is not the issue--I have room to spare on the seat height. It's the clamshell effect. I am aware that seat height and angle are separate functions. I have run all the switches through their entire travel. You cannot get the front of the seat to be level. It is angled up even at it's lowest point. Maybe it's just me but I can't stand feeling like I'm being tilted too far backwards in my seat. It wouldn't be such a big issue if the rear of the seat held my butt up more. I have actually fixed the problem by placing a folded up blanket towards the rear of the seat pad, a bolster so to speak, which raises up my rear and evens out my knee angle. It is 100% more comfortable. I'd recommend anyone out there who is my size and not really enjoying the seats, try this. I am not opposed to Macgyver mods. Since I like the rest of my truck immensely, a few small mods here and there to make it more "comfortable" are perfectly acceptable

Anyone else feel the same way? The padding in the butt area feels way too soft, no support. It just sinks right down. And I'm not a very heavy guy either--5'9 135lb. In the seat, I feel like my knees are unnaturally high. Flexed up. I can't get the front of the seat to angle down enough. It forces your knees up. Your butt sinks down into the padding 2-3 inches. It's giving me leg pain, and it's the only thing I don't like about my truck. It may end up causing me to trade or switch brands. It's really that bad for me. Since I do like everything else about my truck, I've resorted to trying to place additional support in the butt area, blankets, wedges, you name it. None of it really helps that much. Any tips?
